FIGS. 6A and 6B are views illustrating a rear surface and a stand
of the liquid crystal display apparatus of FIG. 2. FIGS. 7 and 8
are perspective views illustrating a mount structure usable with
the liquid crystal display apparatus FIG. 2.
[0057] Referring to FIGS. 2 through 5, the liquid crystal display
apparatus 1 according to an exemplary embodiment includes a display
unit 10 and a housing 20.
[0058] The display unit 10 is configured to display images and
includes a liquid crystal display panel (not illustrated) and a
backlight unit (not illustrated).
[0059] The backlight unit may use a direct-type backlight unit in
which a plurality of light sources is disposed directly below the
liquid crystal display panel. Alternatively, the backlight unit may
use an edge-type backlight unit in which a plurality of light
sources is disposed in a side of the liquid crystal display panel.
When the edge-type backlight unit is used, the plurality of light
sources may be disposed in only one side surface of the liquid
crystal display panel in which a side bezel 33 is provided, and may
not be disposed in the other side surface of the liquid crystal
display panel in which the side bezel 33 is not provided. As
another example, the plurality of light sources may be disposed in
top and bottom side surfaces of the liquid crystal display
panel.
[0060] A controller 50 configured to control the liquid crystal
display panel and the backlight unit may be disposed in a rear
surface of the backlight unit. Software for setting configuration
of the display unit 10 may be installed in a memory (not
illustrated) of the controller 50. Also, the configuration software
may be capable of selecting a screen inversion of the display unit
10. In other words, when rotating the liquid crystal display
apparatus 1 by 180 degrees, a user executes the configuration
software and selects the screen inversion so that the liquid
crystal display apparatus 1 rotated by 180 degrees can display
images in the same way as a non-rotated installed liquid crystal
display apparatus 1.
[0061] Detailed description of the liquid crystal display panel and
backlight unit of the display unit 10 is omitted.
[0062] A black matrix area 34 is formed in an entire circumference
of a front surface of the display unit 10, i.e., in a top edge, a
bottom edge, a left edge, and a right edge of the front surface of
the display unit 10. The black matrix area 34 is formed for shading
the liquid crystal display panel and its width is about 1.5 mm.
[0063] The housing 20 is formed to support and secure the display
unit 10 with sufficient strength. The housing 20 may include an
upper housing 30 and a lower housing 40. The upper housing 30 is
coupled to the lower housing 40. The lower housing 40 is formed to
cover the entire rear surface of the display unit 10, and has
rigidity to stably support the display unit 10.
[0064] The upper housing 30 is formed in a substantially flat
U-shape to be able to cover three edges of the front surface 11 of
the display unit 10. As illustrated in FIG. 5, the upper housing 30
includes an upper housing body 35 formed in a substantially flat
U-shape, a top bezel 31 that extends perpendicularly from the upper
housing body 35 and wraps a top edge of the front surface 11 of the
display unit 10, a bottom bezel 32 that extends perpendicularly
from the upper housing body 35 and wraps a bottom edge of the front
surface 11 of the display unit 10, and a side bezel 33 that extends
perpendicularly from the upper housing body 35 and wraps one side
edge of the front surface 11 of the display unit 10. Accordingly,
the upper housing body 35, the top bezel 31, the bottom bezel 32,
and the side bezel 33 configured of the upper housing 30 is formed
in a single body.
[0065] When the upper housing 30 is connected to the lower housing
40, a portion of the black matrix area 34 formed in the
circumference of the front surface 11 of the display unit 10 is
exposed in the other side surface of the display unit 10 which is
opposite to the one side surface of the display unit 10 wrapped by
the side bezel 33, i.e., in a side surface of the display unit 10
in which a side bezel 33 is not disposed. Thus, the liquid crystal
display apparatus 1 may be implemented to have sufficient
mechanical strength by supporting three sides of the display unit
10 by the upper housing 30 and the lower housing 40.
[0066] The top bezel 31, bottom bezel 32, and side bezel 33 may be
formed to cover the black matrix area 34 and support the display
unit 10 with sufficient rigidity. For example, if a width w of the
black matrix area 34 is about 1.5 mm, each of the top bezel 31,
bottom bezel 32, and side bezel 33 may have a width W of about 4
mm-5 mm.
[0067] A mounting portion 60 is formed in the rear surface 41 of
the housing 20 as illustrated in FIG. 6A, and allows the liquid
crystal display apparatus 1 to be detachably fixed to a stand 90.
The mounting portion 60 is formed in the housing 20 so that, even
when the liquid crystal display apparatus 1 is rotated by 180
degrees, a height from a base surface in which the stand 90 is
disposed to a top end of the liquid crystal display apparatus 1 is
the same as a height when the liquid crystal display apparatus 1 is
not rotated by 180 degrees. Further, the mounting portion 60 is
provided in the rear surface 41 of the housing 20 so that the
height H1 (see FIG. 3) from the base surface to the top end of the
liquid crystal display apparatus 1, when the liquid crystal display
apparatus 1 is fixed to the stand 90 in a non-rotated state, is the
same as the height H2 (see FIG. 3) from the base surface to the top
end of the liquid crystal display apparatus 1, when the liquid
crystal display apparatus 1 is rotated by 180 degrees and fixed to
the stand 90. Therefore, the mounting portion 60 is formed at the
same distance from each of the top end and the bottom end of the
liquid crystal display apparatus 1. In other words, the mounting
portion 60 may be disposed at the same distance from the top bezel
31 and the bottom bezel 32. For example, as illustrated in FIG. 6A,
if the mounting portion 60 is implemented as four vesa mount holes
61 and 62, the distance d1 from the top end of the liquid crystal
display apparatus 1 to the upper vesa mount holes 61 is formed to
be the same as the distance d2 from the bottom end of the liquid
crystal display apparatus 1 to the lower vesa mount holes 62.
[0068] As illustrated in FIG. 6B, if the mounting portion 60 is
implemented as the vesa mount holes 61 and 62, the stand 90 is
provided with a vesa mount 91 having mount holes 91a corresponding
to the vesa mount holes 61 and 62.
[0069] Alternatively, the mounting portion 60 may be implemented as
a detachable mount 93 or a clip mount 96.
[0070] Examples of a liquid crystal display apparatus 1 in which
the detachable mount 93 is disposed and a stand 90 to which the
detachable mount 93 is able to be fixed are illustrated in FIG. 7.
Referring to FIG. 7, the detachable mount 93 includes a fixing
bracket 94 which is secured to the rear surface 41 of the housing
20 of the liquid crystal display apparatus 1, and a fixing hook 95
extending from the fixing bracket 94. The fixing bracket 94 is
screwed into the rear surface 41 of the housing 20. For example,
the fixing bracket 94 may be fixed to the rear surface 41 of the
housing 20 using the vesa mount holes 61 and 62 described above.
The stand 90 is provided with a hook coupling portion 92 to which
the fixing hook 95 can be coupled. Accordingly, if the fixing hook
95 of the detachable mount 93 disposed in the liquid crystal
display apparatus 1 is coupled to the hook coupling portion 92 of
the stand 90, the liquid crystal display apparatus 1 is fixed to
the stand 90.
[0071] If a user wants to turn the liquid crystal display apparatus
1 by 180 degrees, the user may remove the fixing bracket 94 from
the rear surface 41 of the liquid crystal display apparatus 1.
Then, the user turns the liquid crystal display apparatus 1 by 180
degrees, and fixes the fixing bracket 94 to the rear surface 41 of
the housing 20. Subsequently, the user couples the fixing hook 95
of the liquid crystal display apparatus 1 to the hook coupling
portion 92 of the stand 90 so that the liquid crystal display
apparatus 1 is rotated by 180 degrees. At this time, since the
fixing bracket 94 is disposed at the same distance from each of the
top end and the bottom end of the liquid crystal display apparatus
1, even when the liquid crystal display apparatus 1 is rotated by
180 degrees, the height H2 (see FIG. 3) from the base surface to
the top end of the liquid crystal display apparatus 1 is the same
as the height H1 (see FIG. 3) of the liquid crystal display
apparatus 1 which is not rotated by 180 degrees.
[0072] An example of a clip mount 96 and a liquid crystal display
apparatus 1 in which the clip mount 96 can be disposed are
illustrated in FIG. 8. As illustrated in FIG. 8, a clip groove 97
is provided in the rear surface 41 of the housing 20 of the liquid
crystal display apparatus 1. The clip mount 96 includes a clip
portion 98 which is inserted into and coupled to the clip groove 97
of the rear surface 41 of the housing 20, and a fixing hook 99
extending from the clip portion 98. The clip portion 98 and the
clip groove 97 have the same cross-section. Therefore, the clip
portion 98 and the clip groove 97 are formed to be coupled to each
other when the liquid crystal display apparatus 1 is not rotated
and when the liquid crystal display apparatus 1 is rotated by 180
degrees. For example, a cross-section of each of the clip portion
98 and the clip groove 97 may be formed as one of a plurality of
shapes such as a square, a rectangular, a hexagon, an octagon, etc.
At this time, the clip groove 97 is formed at the same distance
from each of the top end and the bottom end of the liquid crystal
display apparatus 1. The fixing hook 99 may be formed in the same
shape as the fixing hook 95 of the detachable mount 93 described
above. Accordingly, the clip mount 96 may be mounted to the hook
coupling portion 92 of the stand 90 as illustrated in FIG. 7. As a
result, if the clip mount 96 as described above is used, the liquid
crystal display apparatus 1 rotated by 180 degrees may be fixed to
the stand 90. Even if the liquid crystal display apparatus 1 is
rotated by 180 degrees, the height H2 (see FIG. 3) from the base
surface to the top end of the liquid crystal display apparatus 1 is
the same as the height H1 (see FIG. 3) of the liquid crystal
display apparatus 1 that is not rotated by 180 degrees.
[0073] Further, as another example, the mounting portion 60 of the
liquid crystal display apparatus 1 may be fixed to a pivot stand
(not illustrated) that can rotate by 180 degrees. In this case, the
liquid crystal display apparatus 1 can be rotated by 180 degrees
without removing the liquid crystal display apparatus 1 from the
pivot stand. Detailed description of the pivot stand is
omitted.
[0074] In another exemplary embodiment, a detachable bezel 70 may
be detachably disposed in the side surface of the display unit 10
in which the side bezel 33 of the liquid crystal display apparatus
1 does not exist. Hereinafter, a liquid crystal display apparatus 1
according to an exemplary embodiment including the detachable bezel
70 will be described in detail with reference to FIGS. 9A through
11C.
[0075] FIG. 9A is a cross-sectional view illustrating the liquid
crystal display apparatus of FIG. 2 to which a detachable bezel is
coupled, and FIG. 9B is a front view of the liquid crystal display
apparatus of FIG. 9A. FIG. 10A is a cross-sectional view
illustrating a state in which a detachable bezel is separated from
the liquid crystal display apparatus of FIG. 9A, and FIG. 10B is a
front view of the liquid crystal display apparatus of FIG. 10A.
FIG. 11A is a front view illustrating a liquid crystal display
apparatus according to another exemplary embodiment, FIG. 11B is a
plan view of the liquid crystal display apparatus of FIG. 11A, and
FIG. 11C is a view illustrating a state in which a detachable bezel
is separated from the liquid crystal display apparatus of FIG.
11A.
[0076] As illustrated in FIGS. 9A and 9B, the detachable bezel 70
is detachably disposed in one side surface of the liquid crystal
display apparatus 1 according to an exemplary embodiment in which
there is no side bezel 33. Accordingly, if the detachable bezel 70
is disposed as illustrated in FIG. 9B, the liquid crystal display
apparatus 1 according to an exemplary embodiment has an appearance
similar to related art liquid crystal display apparatuses having
bezels in four side surfaces thereof.
[0077] If the liquid crystal display apparatuses 1 are desired to
be used as a dual monitor, as illustrated in FIGS. 10A and 10B, the
detachable bezel 70 is removed from the liquid crystal display
apparatus 1. At this time, if a plurality of screws 75 is loosened
from the rear surface 41 of the housing 20, the detachable bezel 70
may be removed from the liquid crystal display apparatus 1. One
example of the removed detachable bezel 70 is illustrated in FIG.
5. Referring to FIG. 5, the detachable bezel 70 is formed in a
substantially flat U shape, an upper arm 71 is formed to have a
length corresponding to a distance D (as shown in FIG. 11C) between
the top bezel 31 and the bottom bezel 32 so as to form a side
bezel, and a lower arm 72 is provided with a plurality of screw
holes 73. A plurality of taps 45 is formed in positions
corresponding to the plurality of screw holes 73 of the detachable
bezel 70 in the lower housing 40. Accordingly, if the detachable
bezel 70 is mounted to the one side surface of the liquid crystal
display apparatus 1 in which there is no side bezel 33 and a
plurality of screws 75 is screwed into the plurality of taps of the
lower housing 40 via the plurality of screw holes 73 of the
detachable bezel 70, the detachable bezel 70 is fixed to the lower
housing 40 as illustrated in FIGS. 9A and 9B. At this time, the
width W1 of the detachable bezel 70 is formed to be the same as the
width W of the side bezel 33 of the upper housing 30.
[0078] FIGS. 11A through 11C illustrate another example of a
detachable bezel 80. If the detachable bezel 80 is disposed in a
side surface of the liquid crystal display apparatus 1 in which
there is no bezel, as illustrated in FIG. 11A, the bezels 31, 32,
33 and 81 exist in the circumference of the front surface 11 of the
liquid crystal display apparatus 1.
[0079] If a user desires to use the liquid crystal display
apparatus 1 according to an exemplary embodiment as a dual monitor,
the user removes the detachable bezel 80 from the liquid crystal
display apparatus 1. At this time, since the detachable bezel 80 is
coupled to the top bezel 31 and the bottom bezel 32 by one touch,
the detachable bezel 80 may be easily removed from the liquid
crystal display apparatus 1 by a user.
[0080] The liquid crystal display apparatus 1 from which the
detachable bezel 80 is removed is illustrated in FIG. 11C.
Referring to FIG. 11C, the detachable bezel 80 is formed in a
substantially L shape, and two fixing protrusions 83 are provided
in a side plate 81 forming the bezel. A projecting portion 81a
having a length corresponding to the distance D between the top
bezel 31 and the bottom bezel 32 and a height corresponding to the
thickness of each of the top bezel 31 and the bottom bezel 32 is
provided between the two fixing protrusions 83. Also, a fixing hole
84 is provided in an end portion of each of the top bezel 31 and
the bottom bezel 32 of the liquid crystal display apparatus 1. At
this time, the fixing protrusions 83 formed in the detachable bezel
70 and the fixing holes 84 provided in the top and bottom bezels 31
and 32 are formed to be coupled to or to be separated from each
other with one touch by a user. Accordingly, if the two fixing
protrusions 83 are inserted into the fixing hole 84 of the top
bezel 31 and the fixing hole 84 of the bottom bezel 32 as
illustrated in FIG. 11B, the detachable bezel 70 is fixed to the
liquid crystal display apparatus 1 as illustrated in FIG. 11A.
[0081] In another exemplary embodiment, both side bezels of the
liquid crystal display apparatus 1 may be formed as detachable
bezels. If both side bezels of the liquid crystal display apparatus
1 are each formed as the detachable bezel, when three or more
liquid crystal display apparatuses 1 are disposed side by side as
illustrated in FIG. 15, the width of the contacting portion between
the three or more liquid crystal display apparatuses 1 may be
minimized.
[0082] The liquid crystal display apparatus 1 having detachable
bezels in both side surfaces will be described in detail with
reference to FIGS. 12A through 14B.
[0083] FIG. 12A is a cross-sectional view illustrating a liquid
crystal display apparatus with two detachable bezels disposed in
both side surfaces thereof according to another exemplary
embodiment, and FIG. 12B is a front view of the liquid crystal
display apparatus of FIG. 12A.
[0084] When a single liquid crystal display apparatus 1 is used, as
illustrated in FIGS. 12A and 12B, the liquid crystal display
apparatus 1 is used in a state in which two detachable bezels 70
and 70' are coupled to the both side surfaces of the liquid crystal
display apparatus 1. At this time, the detachable bezels 70 and 70'
may use bezels having a structure identical or similar to the
detachable bezel 70 as illustrated in FIG. 6.
[0085] In this state, if two liquid crystal display apparatuses 1
are desired to be connected to each other in order to use as a dual
monitor, one detachable bezel 70 is removed from one side surface
of the liquid crystal display apparatus 1. FIG. 13A is a
cross-sectional view illustrating a state in which the detachable
bezel 70 is separated from one side surface of the liquid crystal
display apparatus 1 of FIG. 12A, and FIG. 13B is a front view of
the liquid crystal display apparatus 1 of FIG. 13A.
[0086] As illustrated in FIGS. 13A and 13B, the liquid crystal
display apparatus 1 from which the one side detachable bezel 70 is
removed is the same as the liquid crystal display apparatus 1
having no side bezel at one side of the liquid display apparatus
(as described above with reference to FIGS. 2 and 4). Accordingly,
one liquid crystal display apparatus 1 remains in a non-rotated
state, and the other liquid crystal display apparatus 1 is rotated
by 180 degrees. One side surface of the other liquid crystal
display apparatus 1 in which there is not a side bezel may be
disposed to be in contact with the side surface of the one liquid
crystal display apparatus 1 in which there is not a side bezel,
thereby configuring a dual monitor (as illustrated in FIG. 3).
[0087] In a case in which a triple monitor is configured using
three liquid crystal display apparatuses 1-1, 1-2, and 1-3, two
detachable bezels 70 and 70' are removed from both side surfaces of
a first liquid crystal display apparatus 1-1, a detachable bezel
70' is removed from the right side surface of a second liquid
crystal display apparatus 1-2, and a detachable bezel 70 is removed
from the left side surface of a third liquid crystal display
apparatus 1-3. FIG. 14A is a cross-sectional view illustrating a
state in which detachable bezels are separated from both side
surfaces of the liquid crystal display apparatus of FIG. 12A, and
FIG. 14B is a front view of the liquid crystal display apparatus of
FIG. 14A.
[0088] When both detachable bezels 70 and 70' are removed from both
side surfaces of the first liquid crystal display apparatus 1-1,
only the top bezel 31 and the bottom bezel 32 exist in the first
liquid crystal display apparatus 1-1. In this state, the second
liquid crystal display apparatus 1-2, from which the right
detachable bezel 70' is removed, is connected to the left side
surface of the first liquid crystal display apparatus 1-1 from
which both sides detachable bezels 70 and 70' are removed with a
non-rotated state. After that, the third liquid crystal display
apparatus 1-3, from which the left detachable bezel 70 is removed,
is connected to the right side surface of the first liquid crystal
display apparatus 1-1 from which both sides detachable bezels 70
and 70' are removed with a non-rotated state. As a result, a triple
monitor is configured so that three liquid crystal display
apparatuses 1-1, 1-2 and 1-3 are connected to and in contact with
each other as illustrated in FIG. 15. As described above, if both
side bezels 33 are formed in the detachable bezels 70 and 70', the
liquid crystal display apparatus 1 is not required to be rotated by
180 degrees in order to form a dual monitor configuration or a
triple monitor configuration.
[0089] Hereinafter, a method for setting a dual-monitor using two
liquid crystal display apparatuses 1 according to an exemplary
embodiment will be described in detail with reference to FIG.
16.
[0090] FIG. 16 is a flowchart illustrating a dual monitor setting
method according to an exemplary embodiment.
[0091] First, two liquid crystal display apparatuses, i.e., a first
liquid crystal display apparatus and a second liquid crystal
display apparatus are provided (S161). At this time, each of the
first and second liquid crystal display apparatuses is formed so
that the circumference of a front surface of a display unit is
configured with a top bezel, a bottom bezel, a side bezel, and a
black matrix area.
[0092] The first liquid crystal display apparatus remains coupled
to a stand in a non-rotated state. The non-rotated state refers to
a state in which the liquid crystal display apparatus is not
rotated by 180 degrees. If the first liquid crystal display
apparatus includes a detachable bezel, the detachable bezel is
removed from the first liquid crystal display apparatus so as to
expose the black matrix area.
[0093] Then, the second liquid crystal display apparatus is removed
from the stand (S162). At this time, the second liquid crystal
display apparatus may be removed from the stand using a mounting
portion provided in a rear surface of the second liquid crystal
display apparatus.
[0094] After that, a user rotates the second liquid crystal display
apparatus by 180 degrees, and then fixes the second liquid crystal
display apparatus, which is rotated by 180 degrees, to the stand
(S163). At this time, since the mounting portion of the second
liquid crystal display apparatus is located at the same distance
from each of the top end and the bottom end of the second liquid
crystal display apparatus, even when the second liquid crystal
display apparatus is fixed to the stand in a state rotated by 180
degrees, the height from the base surface to the top end of the
second liquid crystal display apparatus is the same as the height
of the first liquid crystal display apparatus which is not rotated
by 180 degrees. If the second liquid crystal display apparatus
includes a detachable bezel, the detachable bezel is removed from
the second liquid crystal display apparatus so as to expose the
black matrix area.
[0095] Next, the second liquid crystal display apparatus is
disposed at a side of the first liquid crystal display apparatus
(S164). Further, the second liquid crystal display apparatus is
disposed so that the side surface of the second liquid crystal
display apparatus rotated by 180 degrees in which the side bezel
does not exist, i.e., in which the black matrix area exists is in
contact with the side surface of the first liquid crystal display
apparatus in which the side bezel does not exist, i.e., in which
the black matrix area exists. Then, installation of a dual monitor
occurs so that the width of a contacting portion of two liquid
crystal display apparatuses is twice the width w of the black
matrix area as illustrated in FIG. 3.
[0096] Then, the user runs configuration software of the second
liquid crystal display apparatus, which is rotated by 180 degrees,
so as to invert the screen of the second liquid crystal display
apparatus. Detailed description of the configuration software for
inverting the screen of the second liquid crystal display apparatus
is omitted.
[0097] If the dual monitor is configured using the liquid crystal
display apparatuses according to an exemplary embodiment, the width
of a contacting portion in which two liquid crystal display
apparatuses are in contact with each other may be minimized to
twice the width of the black matrix area. Accordingly, images being
displayed on the dual-monitor configured of two liquid crystal
display apparatuses according to an exemplary embodiment may give a
feeling of a more smooth continuous image than an image being
displayed on a related art dual monitor.
[0098] While the exemplary embodiments have been described,
additional variations and modifications of the exemplary
embodiments may occur to those skilled in the art once they learn
the basic inventive concepts. Therefore, it is intended that the
appended claims shall be construed to include both the above
embodiments and all such variations and modifications that fall
within the spirit and scope of the inventive concepts.
